Over time, this residue can easily spoil, affecting the quality of subsequent milk. If milk accumulates for a long time, some substances may accumulate at the bottom of the tank, resulting in uneven milk concentration. Therefore, a closed self-cleaning milk storage tank is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a closed, self-cleaning milk storage tank. (Refer to...) Figure 1 and Figure 4A closed self-cleaning milk storage tank includes a milk storage tank body 1; a top box 2 is bolted to the center of the top of the milk storage tank body 1, and a reciprocating assembly 3 is provided in the inner cavity of the top box 2. The bottom of the reciprocating assembly 3 passes through the top box 2 and the milk storage tank body 1 in sequence and is provided with a stirring and cleaning assembly 4. A support block is bolted to the right side of the milk storage tank body 1, and a water pump 5 is bolted to the top of the support block. The outlet of the water pump 5 is connected to a water outlet pipe, and the left end of the water outlet pipe passes through the milk storage tank body 1 and is connected to a connecting ring 6. Several water outlet holes are opened at the bottom of the connecting ring 6, and the top of the connecting ring 6 is bolted to the top of the inner cavity of the milk storage tank body 1. The inlet of the water pump 5 is connected to a water inlet pipe. When it is necessary to clean the milk storage tank body 1, cleaning water is delivered into the milk storage tank body 1, which improves the cleaning effect of the milk storage tank body 1.

[0024] Reference Figure 2 and Figure 4 The reciprocating assembly 3 includes a first motor 31, a rotating shaft 32, a gear 33, a moving frame 34, and a mounting plate 35. The first motor 31 is bolted to the front of the top box 2. The output shaft of the first motor 31 is fixedly connected to the rotating shaft 32. The back of the rotating shaft 32 is rotatably connected to the back of the inner cavity of the top box 2 via a bearing. The gear 33 is keyed to the surface of the rotating shaft 32. The moving frame 34 is slidably connected to the inner cavity of the top box 2. Teeth are fixedly connected to both sides of the inner cavity of the moving frame 34 from top to bottom, and the teeth cooperate with the gear 33. The gear 33 is located in the inner cavity of the moving frame 34. The mounting plate 35 is bolted to the bottom of the moving frame 34. The reciprocating assembly 4 drives the stirring and cleaning assembly 4 to move back and forth, thereby turning the milk in the milk storage tank body 1 up and down, preventing the accumulation of substances at the bottom of the milk storage tank body 1, and making the milk concentration uniform. At the same time, the scraper 46 can clean the entire inner wall of the milk storage tank body 1 and scrape off the milk. Figure 4 As shown, only a portion of the surface of gear 33 has teeth, and the other portions cannot mesh with the teeth. When gear 33 meshes with the teeth on one side of the inner cavity of the moving frame 34, gear 33 is separated from the teeth on the other side of the inner cavity of the moving frame.

[0025] Reference Figure 2 and Figure 5The stirring and cleaning assembly 4 includes a second motor 41, a connecting shaft 42, a stirring shaft 43, a stirring rod 44, a blade 45, and a scraper 46. The bottom of the mounting plate 35 is bolted to the second motor 41. The output shaft of the second motor 41 is fixedly connected to the connecting shaft 42. The bottom of the connecting shaft 42 extends through the inner cavity of the milk storage tank body 1. The surface of the connecting shaft 42 is sequentially fixedly connected to the stirring shaft 43 from top to bottom. The surface of the stirring shaft 43 is sequentially fixedly connected to the stirring rod 44 from left to right. The side of the stirring rod 44 away from the stirring shaft 43 is fixedly connected to the blade 45. The side of the stirring shaft 43 away from the connecting shaft 42 is bolted to the scraper 46. The side of the scraper 46 away from the stirring shaft 43 contacts the inner wall of the milk storage tank body 1. The scraper 46 stirs the milk in the milk storage tank body 1 and scrapes the milk off the inner wall of the milk storage tank body 1.

[0026] Reference Figure 2 A sealing ring 7 is bonded to the bottom of the inner cavity of the top box 2, and the inner ring of the sealing ring 7 is in contact with the surface of the connecting shaft 42; it seals the gap between the top box 2 and the connecting shaft 42 to prevent milk from entering the top box 2.

[0027] Reference Figure 2 The top box 2 has sliding grooves 8 on both sides of its inner cavity. The inner cavity of the sliding grooves 8 is slidably connected to sliders 9. The opposing sides of the sliders 9 are bolted to the two sides of the mounting plate 35. This limits the mounting plate 35, assists the mounting plate 35 in raising and lowering, and improves the stability of the mounting plate 35.

[0028] Reference Figure 1 The top left side of the milk storage tank body 1 is connected to the feed pipe 10, and the surface of the feed pipe 10 is threaded with a pipe cap. The center of the bottom of the milk storage tank body 1 is connected to the discharge pipe 11, and a valve is installed on the discharge pipe 11.

[0029] Working principle: During use, the user delivers milk to the storage tank through the feed pipe 10. At this time, the user turns on the first motor 31 and the second motor 41. The second motor 41 drives the connecting shaft 42 to rotate, which in turn drives the stirring shaft 43 to rotate. This causes the stirring shaft 43 to drive the stirring rod 44 and the scraper 46 to rotate, and the stirring rod 44 to drive the blades 45 to rotate. The first motor 31 drives the rotating shaft 32 to rotate, which in turn drives the gear 33 to rotate. This causes the gear 33 to drive the moving frame 34 to move up and down repeatedly, which in turn drives the mounting plate 35 to move up and down repeatedly, thereby driving the second motor 41 to move up and down repeatedly, turning the milk up and down to prevent the accumulation of substances at the bottom of the storage tank body 1 and to make the milk concentration uniform. During milk processing, the milk is delivered out of the storage tank body 1 through the discharge pipe 11. When cleaning is required, the user turns on the water pump 5, which delivers water to the connecting ring 6 through the water inlet pipe, and then sprays it into the storage tank body 1 through the water outlet. The stirring and cleaning components 4 move up and down repeatedly to prevent milk residue from remaining on the inner wall of the storage tank body 1.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
